Australia Prime Minister Malcolm Turnbull took a "farewell selfie" with the outgoing US President Barack Obama after they met officially for the final time. The two leaders held a 50-minute meeting in Peru on Sunday (20 November) discussing terrorism, trade and the US-Australia ties at the Asia-Pacific Economic Cooperation (APEC) summit.

PM Turnbull said that his country's alliance with US is "stronger than ever" and thanked Obama for his great leadership. He also described the US president as a "remarkable leader".

"It's a great moment but a sad moment to have our last meeting in your capacity as President of the United States.

"Our alliance has got stronger than ever," Turnbull said, while adding that it was based on "shared values" and a determination to work together around the world "in freedom's cause".

In the closed door talks, the two leaders spoke in favour of free trade, including the Trans Pacific Partnership, contrasting with the campaign rhetoric of US president-elect Donald Trump. They also discussed security issues in the South China Sea and the fight against the Islamic State (Isis).

"We've agreed, as we have with the other leaders here, the importance of making the case for open markets repeatedly and more persuasively now than ever," Turnbull said; while, Obama promised a "strong hand-off" to the receiving Trump government.

"It's a momentous occasion when one president hands over to another. It's a point in history," the Australian premier said after the meeting.

Turnbull also thanked Obama for his co-operation in the resettlement of asylum seekers, who are living in Nauru and Papua New Guinea. The two countries had reached a deal under which the US would accept around 18,000 refugees.
